Pulumi

My preference for Infrastructure as Code (IaC) tools like Terraform and Pulumi enhances my productivity and enables more consistent, fault-tolerant deliveries. This approach allows me to represent infrastructure in code, facilitating progressive growth and better management. By adopting cutting-edge cloud technologies such as Docker, Vagrant, and Ansible, I streamline processes and reduce repetitive tasks, which is crucial in challenging situations and leads to more efficient and reliable cloud solutions.
